Accepted Answer

Seafloor spreading creates new oceanic crust at mid-ocean ridges, driving plate movement.

Answer

Seafloor spreading recycles old oceanic crust at subduction zones, contributing to plate movement.

Answer

Seafloor spreading causes the ocean floor to rise and fall, influencing plate boundaries.

Answer

Seafloor spreading forms and destroys continental crust at convergent plate boundaries, leading to mountain building.

Answer

Animal species presence and distribution

Question 7

Identify and describe the three primary mechanisms that drive the movement of tectonic plates: convection currents, ridge push, and slab pull.

Accepted Answer

Convection currents within the Earth's mantle drive the movement of plates, causing them to diverge at mid-ocean ridges and converge at subduction zones.

Accepted Answer

Ridge push is the force generated by the accumulation of new crustal material at mid-ocean ridges, pushing plates apart.

Accepted Answer

Slab pull is the force that pulls plates towards subduction zones due to the weight and density of the subducting oceanic crust.

Answer

The Earth's rotation directly causes plates to move in a circular pattern.

Question 8

How could climate change impact the spread and number of plant and animal species?

Accepted Answer

Climate change may cause species to move to new areas as they adjust to changing conditions.

Answer

Climate change is unlikely to have a significant impact on the number of plant and animal species.

Answer

Climate change will only affect the spread and number of species that live in water.

Answer

Climate change is not a major concern for protecting plant and animal species.
